65% x 70 = 45.5
The mass of oxygen in his body is 45.5 kg
Answer:
18%
Explanation:
There are two equal and opposite forces on a floating object: weight and buoyancy.
W = B
The weight of an object is its mass times gravity: W = mg
Buoyancy is the weight of the displaced fluid: W = mf g
Plugging in:
mg = mf g
m = mf
Mass is density times volume:
ρV = ρf Vf
Solving for the ratio of Vf / V:
Vf / V = ρ / ρf
Given that ρ = 0.82 g/mL and ρf = 1.00 g/mL:
Vf / V = 0.82
That means 82% of the object's volume (and therefore, 82% of its mass, assuming uniform density) is submerged. Which means that 18% is above the water line.
Answer:
In my opinion, I think we do change when people come to our lives because the way we feel around people makes us feel a certain way around all people in our lives in a good way. They can change our lives by being there and helping us physically and mentally. We do have the choice to follow what someone is trying to change us. Example if we have a problem like addiction, we can choose to get help from anyone or choose not to. Traumas can affect us, but we need to seek help to not fear those problems anymore, thats why people who care about us really want us to change our way of health, addictions, and mental health. For me, as a child my dad was deported because he got a dui and decided for as punishment to be deported or to have a life sentence in the U.S. My mom suffered addiction to drugs and alcohol. I lived with my grandparents for almost my whole childhood untill the age of 9. Then my aunt got engaged and my new uncle decided to take us in because DC.S foound out that me and my other sibling weren't in school at all. Like we never attended school. So we were going to be seperated and taken for adoption untill my uncle had the heart to adopt us and here I am today. He gave us a better life because I finally experienced school,clothes, food, and a safer place to live. All the things I went through even abuse. He changed my life and we changed his. He cares about us, we helped him quit drinking, and that impacts him a lot to open up his heart and quit drinking.
Explanation:
Answer:
13.18m/s²
Explanation:
According to Newton's second law of motion
Force = Mass * acceleration
Given
Mass = 11kg
Force = 145N
Required
acceleration
From the formula
Acceleration = Force/Mass
Acceleration = 145/11
Acceleration = 13.18m/s²
Hence the initial acceleration of the object is 13.18m/s²
